COMBINED VISE AND DRILL.

Specification of Letters Patent.

Patented Sept. 11, 1906.

Application filed December 4, 1905. Serial No. 290,228.

To all whom it may concern.-

Be it known that I, PHILIP J. Human, of Bloomfield,in the county ofGreene and State of Indiana, have invented certain new and usefulImprovements in a Combined Vise and Drill; and I do hereby declare thefollowing to be a full, clear, and exact description of the invention,such as Will enable others skilled in the art to which it appertains tomake and use the same.

The object of this invention is to improve the construction of acombined vise and drill of the character embraced by Letters Patent No.566,170, issued to me August 18, 1896, to the end that the parts may bemore cheaply manufactured, more easily adjusted, and more securely heldin place.

The invention will be hereinafter fully set forth, and particularlypointed out in the claims.

In the accompanying drawings, Figure 1 is a side elevation. Fig. 2 is aplan view, with the anvil in section, on line 2 2, Fig. 1. Figs. 3 and 4are cross-sectional views on lines3. 3 and 4. 1, Fig. 2.

Referring to the drawings, 1 designates an anvil from one end of whichextends a pointed lug 2 and from the other end an overhanging arm,forming the stationary jaw 3 of the vise, the movable or adjustable jaw4: being mounted on an adjustable supporting-bar 5, which fits in thebody of the anvil. As is well known, the latter is permanently securedto any suitable base, and on its bottom at one end on opposite sides ofa longitudinal opening are two opposite lugs 6, while within the anvilat about the center thereof is a guideplate 7, with which the upperportion of the supporting-bar 5 is designed to engage, being guidedthereby. This supporting-bar 5 is of I shape in cross-section, and theadjustable aw I is formed at its bottom with curved arms, which hug theupper laterals and web, so that by turning the screw 8, working in avertical post 9, fixedly mounted on said bar, the adjustable jaw may bemoved toward or away from the stationaryjaw. The base of the I- bar 5 isformed with edge recesses 10 to accommodate the oppositely-disposed lugs6. The space between the top of the I-bar and the roof of the openingsin the end wall and plate 7 is suflicient to enable the supportingbar tobe lifted just suflicient to disengage opposite recesses from the lugs6, permitting the bar to be moved farther inward or outward, accordingto the space which it is desired to secure between'the jaws of the vise.The final adjustment or binding of the jaws is secured, of course, bythe adjustment of the movable jaw on its supporting-bar. Thus it will beseen that by making the supportingbar of I shape I am enabled to formthelocking-recesses which engage the lugs of the anvil in the oppositeedges of the base of the bar, that the upper laterals and web of thisbar form the retaining agency for the movable jaw, and that the bar isheld as against lateral displacement by reason of its upper lateralsbeing in close relation to the walls of the openings formed in thecentral guideplate 7 and in the end of the anvil.

As in my Patent No. 652,674, dated June 26, 1900, I have indicated adrill-socket 12 with its stem passing through the adjustingscrew 8. I

I claim as my invention 1. The combination with the anvil having anoverhanging jaw and a longitudinal Open ing with oppositely-disposedlugs at the base of the anvil, of the supporting-bar of I shape incross-section having edge recesses at its base for engaging with saidlugs, said bar fitting in said opening, and the adjustable jaw movablymounted on said supporting-bar.

2. The combination with the stationary an vil having an overhanging jaw, a longitudinal opening, a guide-plate therein, andoppositelydisposed lugs at the sides of such opening, at the base of theanvil, of the I-shaped supporting-bar designed to extend into saidopening and be guided by said plate, said bar having oppositeedge-recesses in its base for inter locking with said lugs, theadjustable jaw havingrcurved arms hugging the upper laterals and web ofsaid bar, and a screw mounted on said bar for engaging and moving said,

adjustable jaw.

In testimony whereof I have signed this specification in the presence oftwo subscribing witnesses.
